Motherboard connection problems

April 13, 2010 at 05:38:19
Specs: Windows XP, AMD Sempron 1.8 Ghz/1GB and 256MB
I have an Asus p4s533-x with 450watts power supply.

I have enough power to power the motherboard but when i connect the cables and everything the computer works. I also dont know which pin connectors (the ones that are for the lights in the front panel) go to which pins.

The pins on the board should be labeled. Pay close attention to polarity...if you mix the positive & negative, the LEDs won't work. If the pins aren't labeled, check the motherboard manual. If you don't have the manual, go to the Asus website & download a copy.

Will not having those pins connected not send a signal to my monitor?

I have one of them connected and that is just to turn the computer on and off.

I will get the manual as soon as i can and I will connect my pins.

"Will not having those pins connected not send a signal to my monitor?"

No, not as long as you have the power switch connected properly. When you hit the power button, does the system come on & fans spin up?

No signal to the monitor usually means there's a problem with the video card.

The fans do power on and the fans do spin. The video card should be fine. I had switched out motherboards from one dell computer to another E machines computer that I have. I'm just not sure why their isnt a signal to the monitor. The monitor works also because Its used nearly everyday.

I have the computer in front of me and just need help troubleshooting now.

You definitely need to check the manual - if you are using an
AGP graphics card your board only supports 4xAGP 1.5v cards -
you need to check the card you're using as that would be a good
reason why you're getting no signal to the monitor.

its an onboard graphics card.
It was working the other day but once i took the MOBO out and switched the case it was in it didnt start.

Edit: Do I need to have the same power supply that the computer came in? I'm questionable about that.

I resolved my problem. I removed my processor just to llok at it and didnt put it back in correctly so that is what seemed to have messed me up. Now it works!

However I have another problem that I will start another thread to. Thankas for the help guys. I'll keep your tips in mind.

You can't simply swap the board/CPU & expect the system to boot into Windows. It's configured to the old hardware. Windows will have to be reinstalled using the "repair" method. I just replied to your other thread about it.
